Aquarium Airlift and Intake Filter

Aquarium Airlfit Version 1. Using this to move water into a small ebb/flow filter system, on a 2.5 gallon desktop aquaponic setup. See in use here, http://www.gardenisto.com/cultivation/horticulture/desktop-aquaponic-tank-part-1/

I have other stuff on the site for download, like the u siphon I use. It's simple and functional. Please post your prints and let me know of any improvements. Thanks.
